EOCD Signature errors with Archive::Zip

[PK]

I'm getting "can't find EOCD signature" errors from Archive::Zip 1.16 on
files that seem to be valid i.e. I can open them fine with WinZip. Anyone
know why this might be?

I don't really know - though the error presumably comes from the
_findEndOfCentralDirectory() subroutine in Zip.pm. Looks like that sub scans
the zip file for the string that has been assigned to the constant
Archive::Zip::END_OF_CENTRAL_DIRECTORY_SIGNATURE_S TRING, and if it doesn't
find that string, it then throws that error.

I guess, therefore, that if WinZip also looks for the EOCD signature (which
seems to me a reasonable assumption), it must be looking for (and finding) a
different string than that being sought by Archive::Zip.

Can you upload a small zip file (that demonstrates the problem) to somewhere
on the web so that others can get a copy of it ?
How are these zip files being created ?
